2818 10 11 — Artificial corundum, whether or not chemically defined, with < 50 % of the total weight having a particle size > 10 mm (excl. with aluminium oxide content < 98.5% by weight)

2818 Artificial corundum of certain or undetermined chemical composition; aluminum oxide; aluminum hydroxide: 2818 10 – artificial corundum of certain or indefinite chemical composition 2818 20 – aluminum oxide other than artificial corundum 2818 30 – aluminum hydroxide

(A) Artificial Corundum is prepared by melting aluminum oxide in an electric furnace. Aluminum oxide may contain small amounts of other oxides (e.g., titanium and chromium oxides) obtained from the natural material (boxites) or added to improve properties, for example, the hardness of the melted grains or change their color. However, mechanical mixtures of artificial corundum with other substances such as zirconium dioxide are excluded (heading 3824). Artificial corundum comes in the form of small pieces or mass, crushed or in grains; it is more resistant than conventional aluminum oxide to the action of air and acids and is very hard. It is used, for example, as an abrasive material, in the production of refractory conglomerates (such as mullite and sillimanite, which are mixtures of corundum with pure refractory clay and with anhydrous aluminum silicates, respectively), or in laboratory dishes and in the electrical industry. (B) Aluminum oxide, EXCELLENT FROM ARTIFUL CORUND Aluminum oxide (anhydrous or calcified aluminum oxide) (Al2O3) is prepared by calcination of aluminum hydroxide, described below, or from aluminum alum. Light white powder, insoluble in water, specific gravity of about 3.7. It is used, for example, in the metal of gya aluminum, as a filler for paints, in the production of abrasives and artificial precious or semi-precious stones (rubys, sapphires, emeralds, amethysts, aquamarines and others), as a dehydrating agent (for drying gases) and as a catalyst (in the production of acetone and acetic acid, in cracking processes and others).

(C) ALUMINIUM HYDROXIDE Aluminium hydroxide (hydrated alumina) (Al2O3·3H2O) is obtained from bauxite (a mixture containing aluminium hydroxide) in the metallurgical production of aluminium (see the General Explanatory Note to Chapter 76). The dry hydroxide is an amorphous, friable white powder, insoluble in water; the moist hydroxide is a gelatinous mass (alumina gel, gelatinous alumina). It is used in the manufacture of ceramic glazes, printing inks, medicaments, alums, the artificial corundum described above and for clarifying liquids; mixed with carbon, it is used for making anti-corrosion paints, and, owing to its affinity for organic colouring matter, it is also used for preparing the colour lakes of heading 3205 and as a mordant in the textile industry. The aluminates of heading 2841 correspond to this amphoteric hydroxide. This heading also covers activated alumina, obtained by controlled heat treatment of hydrated alumina, which thereby loses most of its water of constitution; activated alumina is used mainly as an adsorbent or as a catalyst. The heading excludes: (a) natural corundum (natural aluminium oxide) and emery (aluminium oxide containing iron oxide) (heading 2513); (b) bauxite, wet or dry, calcined or not calcined, but not chemically purified (e.g., by treatment with soda), used as an electrolyte (heading 2606); (c) activated bauxite (heading 3802); (d) colloidal solutions of aluminium hydroxide (soluble alumina) (heading 3824); (e) artificial corundum on a base of paper, paperboard or other materials (heading 6805) or agglomerated in the form of grinding wheels, whetstones, millstones and similar articles of heading 6804; (f) natural precious or semi-precious stones based on aluminium oxide (heading 7103 or 7105); (g) synthetic precious or semi-precious stones based on aluminium oxide (e.g., synthetic rubies) (heading 7104 or 7105).
